So after several coin tosses and a round of eeny meeny miney moe... The Peanut Butter Biscuits won.
Dogs do not "taste" the same way we do. In fact, they have 1/6th the amount of taste buds that humans have; about 1,700 as opposed to 9,000 in humans. A dogs sense of smell, however, kind of makes up for the lack of taste buds. Since, you cannot "smell" salt, nor can one "smell" sugar... They are completely unnecessary ingredients when it comes to dog treats. Since both of these can be detrimental to the health of your canine pal, it's best just to leave them out.
The key to a good dog treat is smell. The more "aromatic" your dog treat, the more they will enjoy it. Peanut Butter or Hazelnut Butter are excellent additions to these canine crunchables. Does your dog not care for peanut butter? That's OK, you can substitute 4 ounces of shredded Cheddar for the Peanut Butter and make Cheese Biscuits. Neat-o Frito, huh?
Why am I so stuck on uncommon flours for my dog treats. They tend to be whole grain flours instead of refined as wheat so often is, and they are either gluten-free or only contain minuscule amounts. Gluten intolerance in dogs seems to be on the rise. Otto, my previous companion, had gluten issues (it caused hot spots) so I am not taking any chances.
